WISeKey, SEALSQ set up Quantisimo SPV for $575M merger deal (WKEY:NASDAQ)

WISeKey International and SEALSQ Corp have set up a special purpose vehicle, Quantisimo, to pursue a merger with blank-check company GigCapital8. The deal targets an enterprise value of $575 million and a Nasdaq listing for a combined quantum computing platform, the companies said in a statement.

WISeKey, based in Switzerland, provides cybersecurity and IoT solutions. Its shares trade on Nasdaq under WKEY. SEALSQ, also Swiss, develops semiconductors and post-quantum security technology. It trades on Nasdaq under LAES. Both companies have been investing in quantum-safe cryptography and quantum computing research.

Quantisimo signed a letter of intent to merge with GigCapital8. The SPV structure allows WISeKey and SEALSQ to contribute their quantum-related assets and intellectual property into a single entity that will go public through the SPAC merger. The combined company is expected to trade on Nasdaq under a new ticker. GigCapital8 is a blank-check company that raised capital in a 2021 IPO and has been searching for a merger target in the technology space.

The transaction gives WISeKey and SEALSQ a public vehicle for their quantum computing efforts without a traditional IPO. Quantum computing is expensive and slow to commercialize. Public market funding for the sector is scarce. A Nasdaq listing could provide access to deeper capital markets and a broader investor base. The companies have set a valuation target of $575 million at close, with a longer-term goal of reaching $2 billion in enterprise value. WISeKey brings cybersecurity and IoT expertise. SEALSQ contributes semiconductor and quantum-safe technology. The combined platform aims to address both hardware and software layers of quantum computing.

SPAC mergers carry execution risk. Shareholder approval from GigCapital8's existing investors is required. The deal also needs regulatory clearance. WISeKey and SEALSQ have not disclosed a timeline for closing. The LOI is non-binding, meaning either party could walk away before a definitive agreement is signed. The SPAC market has cooled since 2021, and many deals have been terminated or renegotiated. Investors will watch for the quality of the investor base in the PIPE financing, if any.

The SPV structure isolates the quantum assets from WISeKey and SEALSQ's core businesses. This could reduce risk for shareholders of the parent companies while giving Quantisimo its own equity currency for future acquisitions or partnerships.

The next concrete step is a definitive merger agreement. Once signed, the companies will file a proxy statement with the SEC and set a shareholder vote. WISeKey and SEALSQ have not said when they expect that vote. The deal is expected to close in the second half of 2025, though no official timeline has been given.

The companies said the merger would create a pure-play quantum computing platform on Nasdaq. For WISeKey and SEALSQ shareholders, the deal offers a way to participate in quantum computing's upside without the dilution of a traditional IPO.
